##### 一、网关模块搭建 #####

###### 1. 引入依赖 ######

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.3.2.RELEASE</version>
            <relativePath/> 
        </parent>
        
        <properties>
            <spring.cloud-version>Hoxton.SR9</spring.cloud-version>
        </properties>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-gateway</artifactId>
            </dependency>
        </dependencies>
    
        <dependencyManagement>
            
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>${spring.cloud-version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>

###### 2. 配置 ######

访问`product.gblfy.com**`就会路由到`http://localhost:9000`  
这里的9000端口我们的产品服务模块

server:
      port: 8081
    spring:
      cloud:
        gateway:
          routes:
            - id: product
              uri: http://localhost:9000
              predicates:
                - Host=product.gblfy.com**

###### 3. 启动类 ######

package com.gblfy.gatewayserv;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class GatewayServApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(GatewayServApplication.class, args);
        }
    
    }

##### 二、产品服务模块搭建 #####

###### 2.1. 引入依赖 ######

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.3.2.RELEASE</version>
            <relativePath/> 
        </parent>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            </dependency>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
        </dependencies>
        <dependencyManagement>
            <dependencies>
                
                <dependency>
                    <groupId>com.alibaba.cloud</groupId>
                    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                    <version>2.2.6.RELEASE</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>

###### 2.2. 配置 ######

server:
      port: 9000
    management:
      endpoints:
        web:
          exposure:
            include: '*'
    spring:
      cloud:
        nacos:
          discovery:
            service: product-serv
          server-addr: localhost:8848

###### 2.3. 控制层 ######

package com.gblfy.controller;
    
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class ProductController { 
    
        //http://localhost:9000/product/" + productId @GetMapping("/product/{ productId}") public String getProductName(@PathVariable Integer productId) { return "IPhone 12";
        }
    }

###### 2.4. 启动类 ######

package com.gblfy;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class ProductAplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(ProductAplication.class);
        }
    }

###### 2.5. 启动产品模块 ######

###### 4.2. 网关访问产品 ######

通过网关gateway访问产品模块服务  
[http://product.gblfy.com:8081/product/1][http_product.gblfy.com_8081_product_1]
